Field Flattener Lens System Delivers Sharp Images all the Way to the Periphery
Nikon’s innovative Field Flattener Lens System ensures absolutely sharp images throughout the entire field of view. Curvature of field is an aberration that occurs when focusing on the centre of the viewing field, causing the periphery to go out of focus or vice versa. Nikon’s Field Flattener Lens System provides consistent, edge-to-edge sharpness while compensating astigmatism and coma aberration at the same time, offering an exceptionally sharp, clear image throughout the entire field of view.
Advanced Apochromat Optical System with ED (Extra-low Dispersion) Glass Minimizes Colour Fringing to the Furthest Limit of the Visible Light Range
Nikon’s ED (Extra-low Dispersion) glass ensures a contrast-rich and colour-faithful field of view. By designing the entire optical system from the ground up, Nikon’s Advanced Apochromat Optical System corrects not only chromatic aberrations of red, blue and green but also violet chromatic aberration to the furthest limits of the visible light range. The result is unimaginably sharp, high-contrast views.
Multilayer Coating for Natural Colour Fidelity
Multilayer coating is applied to all lens and prism surfaces, allowing powerful light transmission. The resulting bright field of view delivers true-to-life natural colours. Coating also greatly reduces the flare and ghosting that can occur in backlit situations.
Total Reflection Prism for an Incredibly Bright, Clear View
The straight body MONARCH Fieldscope models utilize a Porro prism design, while the angled-type models employ Nikon’s original total reflection prism. Because all prism reflective surfaces offer complete reflectivity with no loss of light, a bright and vivid view is achieved.
Optimized Focusing System for Fast Focusing
The focus ring of MONARCH Fieldscopes provides different focusing speeds for optimal operation: fine focus adjustment for distant subjects and coarser adjustment for nearby subjects. Effortless, smooth focusing enables you to confidently acquire your target faster and in sharper focus.
Newly Designed MONARCH Fieldscope MEP Eyepieces Deliver High Optical Performance
Nikon has developed eyepieces exclusively for MONARCH Fieldscopes. Each employs a new optical system, and a Field Flattener Lens System that delivers consistent sharpness and clarity across the entire field of view. Engineered to provide a wide field of view, MONARCH eyepieces also provide sufficiently long eye relief. Thus, not only do you enjoy peerless viewing — you can also perform collimate photography with a compact digital camera. When attached to a Fieldscope, each of the three new MEP eyepieces are waterproof, ensuring safe use even during unexpected weather changes.
Body Design for Comfortable Observation
The MONARCH Fieldscope body, constructed of robust aluminum alloy, provides durability, reliability and ease of operation. Other ergonomic features such as the specific knurling pattern on the focusing ring enhances its operability. The Type 1 Bayonet Mount with locking system makes eyepiece attachment/detachment easy and secure.
